本文提出了一种描述中心扩张群的方法，即确定与 quandles 相关的伴随群。此外，我们明确描述了某些 quandles 的此类群。作为推论，我们确定了某些二阶 quandle 同调。

15 pages, and no figure. This paper is an algebraic part of the previous paper, arXiv:1210.6528, into which I divided as two parts. Furthermore, I rewrote the introduction in the first version, and revised some statements on Symplectic quandles and Coxeter quandles
